Abstract

Un aparato (100) para aislar un dispositivo (110) intolerante al ruido desde una fuente de ruido, el cual incluye una barra colectora (104/105) digital. Un procesador (101) emite senales de reloj y primeras senales de datos y recibe segundas senales de datos sobre la barra colectora (104/105) digital. Una memoria (109) bi-direccional se acopla entre la barra colectora (104/105) digital y el dispositivo (100) de intolerancia al ruido dispuesto en el modulo de sintonizacion. El aparato (100) opera de tal forma que dependiendo de la senal de reloj, la memoria (109) bi-direccional pasa en forma selectiva las senales de reloj y las primeras senales de datos desde la barra colectora (104/105) digital del dispositivo de intolerancia al ruido, y las segundas senales de datos desde el dispositivo (110) de intolerancia al ruido de la barra colectora (104/105) digital.
